ROLLS FORROLLING STEEL WHEELS AND WHEEL-CENTERS.

Specification of Letters Patent.

Serial No. 560,645.

To all Iwhom 'it may concern.

Be it known that l, CLAr'on l-Vrr'rna, a citizen ot' the United States` residinf.,T in Burnlnunlililn countyP Pennsylvania, have invented certain Improvements in Rolls Ator Rolling Steel Wheels and Wheel-Centers, ot which the following is a specification.

The object of my invention is to construct rolls for rolling steel wheels and wheel centers in such a manner that the hearing ot' the roll upon the inner edge o't' rim and weh of the wheel or wheel center `can loe varied to roll any diameter o't' wheel or wheel center, with any desired width or thickness` of rim, and the roll for rolling the tread surface cf the rim of the wheel can he varied without changing7 the rolls which act upon the inner edge ol the rim and the weh ot' the wheel or wheel center.

ln the accompanying drawingz-Figure l.v is a sectional view throtigh the peripheral roll and the side hearingr rolls and illustrat ing;f the wheel in position; and Fig is a view sii-nilar to Fig. l, showingl a ditlierem diameter of wheel.

is the roll, preterahl).v having a tace L recessed at a tio form the tread and flange of the wheel. The recess can he any depth, which is less than the thickness ot' rim to he rolled.

l and C are the two side rollinzgY rolls having faces and c, respectively1 which hear upon the web (l of the wheel.

It will be noticed that the rolls B and C bear upon the inner edge of the rim of the wheel or wheel center and on the weh d, hut not on the hah (l: of the wheel or wheel center, and the one. function ot' these,

two rolls is to compress the weh and rim` therehy reducing the section o't' blank and increasing the diameter of wheel or wheel ln order to provide. for wheels of ing sections B and C in 'the side rolls B and C,Y respectively, givii'igr rolls B and C a larger bearing surface on web rl, this heiner permissible on account ot increased size ol pressed lila-nk.

The section B has a hearing ange b which alines with the tace Y) of the roll and Yis practically a continuation ot' it, and it also has a screw threaded extension b2 which is adapted to a threaded recess o3 in the rolls B, and, in order to resist anv strains, I provide an annular rib b* on the section B', which is adapted to an annular 'recess ff. kevways are t'ormed in the threaded extension /ff and the walls et the thread# ed recess li Vtor z key 'l'. When the section l is screwed into positior i., turns with the roll l and forms a camtinuation ot' the hearingr face l1. as shown in Fie'. l. 'l'here mav he any numher of these sections as desired. and the width of the hearing?Y tace 1) may he varied.

'l`hc section t. has a hearing: face c, an annular rih e. and a threaded extension c2 adapted to a threaded opening c in the roll t` and is held in position h v a key .Xs shown iu Fig. 2. the sections and t have heen removed in order to aecommodate a wheel of the smallest diameter.

'l`he rolls l) and have hearingl faces c. c'. respectively. which rest against the sides a ot' the roll .L and it will he noticed that there is a clear space hetween the peripher)Y nl' the roll and the enlarged portions ot'. the rolls l and C and that these iin-lined roll` hear upon the inner edge of the rim ol' the wheel or w'hcel center and on the weh fl. so that hv this arrangement the roll A can he removed and another roll suhstituted having' a dillerenl contour or width and depth of recess fl, when it is -desired to alter the size and shape of the wheel or wheel center to he rolled1 without cli-angine the rolls l and C.

It will he understood that wheels may vary in the width ot the tread and thickness of rim, as well as diameter, without atl'ecting the thickness ot' the web.

By this invention one set of rolls B and C may he used for all sizes ot wheels and wheel centers, with all variations as to width and thickness ot' rims and web (l, and all that is necessary is to change the hearing' sections B and C. and, it the tread surface oll the wheel is of different width" the peripheral roll A can be changed to suit. r

In the present. instance the wheel an wheel -center blank is properly termed hetween the dies in a machine and then introduced in a machine. having the rolls as above set forth, the roll A shaping the tread of the wheel or wheel center and the ioo rolls Bv end C sheping the inner edge of the rim and rolling the web d to any desired thickness.

I claimzl A side bearinorollenfor maohines of the character descried, suidroller having two bearing faces, one 'back of the other, .the rear bearing face being arranged to rest against the sides of the roll which forms the tread and flange of the wheeLthe forward bearing face being shaped to roll the web of the wheel,vvv seid roller" having n threaded recess at its outer, end, a section having a bearing fece forming a continuation of 'the'o'rward bearing face of the body porton of the roller and having a; reduced threaded extension adapted to the recess in ,the body portion, and an annular tongue'on one of said parts extending into an annular groove on the other part. l In testimony whereof, I have signed my nemev to this specification, in the presence of two subscribing Witnesses.
